Answer:
x=23
Step-by-step explanation:
x+15=38 (we subtract 15 from both sides to get x alone on one side)
x=23
Answer:
5 and 11
Step-by-step explanation:
The area of a trapezoid is
A = 1/2 (b1+b2)*h
We know the height is 8 and the area is 64.
Let one of the bases is b and the other is b+6
64 = 1/2 (b+ b+6) *8
Combine like terms
64 = 4 (2b+6)
Divide each side by 4
64/4 = 4/4 *(2b+6)
16 = 2b+6
Subtract 6 from each side
16-6 = 2b+6-6
10 =2b
Divide each side by2
10/2 =2b/2
5=b
The second base is
5+6 =11
Answer:
The answer to your question is Equations 1, 2 and 5 are equivalent
Step-by-step explanation:
1.- Equation 1
2 + x = 5 x = 5 - 2 x = 3
2.- Equation 2
x + 1 = 4 x = 4 - 1 x = 3
3.- Equation 3
9 + x = 6 x = 6 - 9 x = -3
4.- Equation 4
x + (-4) = 7 x - 4 = 7 x = 7 + 4 x = 11
5.- Equation 5
-5 + x = -2 x = 5 - 2 x = 3
